Our Specialty Roofing Services in South Shore
Modified Bitumen Roofing
Modified bitumen is our most-specified membrane for South Shore greystone flat roofs, and for good reason. The SBS-modified asphalt stands up to the freeze-thaw cycling that hits 40 or more times each Chicago winter, and the reinforced cap sheet resists the alligatoring we see on aging built-up roofs after years of UV and lake-driven moisture exposure. On a 1920s greystone two-flat near 71st Street, we replaced a failing built-up roof that had alligatoring and open seams from decades of ponding. The owner had ignored ceiling stains for years; we installed a new modified-bitumen membrane with reinforced flashing at the parapet to withstand South Shore’s freeze-thaw and lake winds. A typical modified bitumen replacement on a South Shore two-flat runs $12,000-$18,000.

Built-Up Roofing (BUR)
Built-up roofing still covers many of South Shore’s 1910-1945 courtyard apartments and three-flats, and when it’s maintained, it can last. The problem we see on lakefront-exposed buildings is chronic ponding after storms, combined with thermal stress from unobstructed winds off Lake Michigan. That standing water finds open seams, and freeze-thaw opens them wider. We repair BUR systems where possible - re-flashing parapets, addressing blisters, adding flood coats - but when the membrane has alligatored through, replacement is the honest recommendation. BUR replacement on a South Shore three-flat typically ranges $10,000-$16,000; spot repairs run $1,200-$3,500.

TPO Roofing
TPO single-ply membrane brings white-reflective energy efficiency to South Shore flat roofs, a real consideration for landlords and owner-occupants watching cooling costs in brick buildings that absorb summer heat. The heat-welded seams hold up well to Chicago’s temperature swings, and the reflective surface reduces thermal cycling stress. We install TPO from authorized manufacturer lines including GAF and CertainTeed, with proper fastening systems rated for the sustained winds that come off the lake. TPO installation on a South Shore two-flat generally runs $14,000-$22,000.

EPDM Roofing
EPDM rubber membrane remains a cost-effective choice for South Shore’s smaller flat roofs - rear porches, garage roofs, additions on bungalows near 75th Street. The black surface absorbs winter heat, which can help with snow melt, though it adds to cooling load in summer. We install fully adhered and mechanically attached systems with seam tape rated for the temperature extremes of lakefront Chicago. EPDM runs $8,500-$14,000 for typical South Shore applications.

Common Specialty Roofing Problems We See in South Shore Homes
- Parapet-wall flashing failure on greystone flat roofs. On the two-flats and three-flats that stack along streets like 71st and 75th, parapet-wall flashing and built-up membrane seams are the first failure point. Decades of ponded water combined with lake-wind thermal stress causes open seams and alligatoring that absentee landlords miss entirely until water damage appears on second-floor ceilings.
- Alligatoring and open seams on lakefront-exposed membranes. South Shore’s direct Lake Michigan exposure means more UV-plus-moisture degradation than any inland South Side neighborhood. Built-up roofs that might last 25 years in Greater Grand Crossing often show advanced cracking here in 18.
- Ice dam intrusion at bungalow eaves. Chicago-style bungalows throughout South Shore have low-pitch rooflines and minimal overhangs. Freeze-thaw cycles push meltwater back under shingles at the eaves, causing interior water damage that homeowners mistake for a plumbing leak.
- Chronic ponding from lake-driven storm events. South Shore’s early-20th-century greystone two-flats and three-flats have flat roofs with built-up or modified-bitumen membranes that are uniquely vulnerable to chronic ponding from lake-driven storms, a failure pattern rarely seen in neighborhoods shielded from the lakefront. Standing water accelerates seam failure and adds structural load that older roof decks weren’t designed to carry indefinitely.

FAQs - Specialty Roofing in South Shore
Direct Lake Michigan exposure subjects South Shore to stronger sustained winds, more wind-driven rain and snow, and harsher freeze-thaw cycling than any inland South Side neighborhood. The unobstructed lake winds accelerate UV and moisture degradation on flat membranes, while chronic ponding after storms finds every open seam. A greystone two-flat half a mile inland in Greater Grand Crossing simply doesn’t face the same thermal and moisture stress. If you’re seeing ceiling stains, call (855) 641-3418 - we’ll inspect and tell you honestly whether repair or replacement makes sense.
Modified bitumen is our most common specification for South Shore greystones. The SBS-modified asphalt handles freeze-thaw cycling better than traditional built-up roofing, and the reinforced cap sheet resists the alligatoring we see after years of lakefront UV exposure. For owners prioritizing energy efficiency, TPO is a strong alternative with heat-welded seams that hold up to Chicago’s temperature swings. We install both from authorized GAF and Atlas lines, and we’ll recommend based on your building’s condition, not our margin. Call for a free estimate.
Parapet flashing can often be repaired if caught early - re-flashing, sealing open seams, adding protective coping metal. But when the membrane behind the flashing has alligatored or the deck is saturated, repair becomes throwing good money after bad. We photograph the condition and show you exactly what we found. Most parapet repairs run $1,200-$3,500; if the whole membrane is failing, replacement is the honest call. Estimates are free - call (855) 641-3418.
Twice yearly: once in spring after freeze-thaw season, once in fall before winter. South Shore’s lakefront exposure means more aggressive weathering, and flat roofs hide problems until water shows on ceilings. Our $89 Seasonal Tune-Up includes photo-documented inspection from the roof surface, not the driveway. For greystone two-flats with absentee ownership, we recommend quarterly checks - the failure pattern on these buildings is predictable, but only if someone is looking. Call to schedule.
We install modified bitumen from GAF and Atlas, both authorized lines we stock locally for South Shore customers. GAF’s SBS-modified systems have strong track records in Chicago’s freeze-thaw climate, and Atlas offers reinforced cap sheets that handle sustained wind exposure well. We don’t substitute brands mid-job. The product specified is the product installed. For a brand-specific recommendation based on your roof’s condition, call (855) 641-3418 for a free estimate.
